i wanna two dimmer control through ir remote pl help me as soon as possible .my problem is i control two dimmer easily but only one remote button but i want press one button then one dimmer is on and then press two button second dimmer is on.but in my case when press one button the two dimmer is on .pl help me as soon as possible.

Hi, this circuit don't work in case connected to ceiling fan where only one wire is coming into the switch board and another wire from fan goes directly to common connection. This circuit only works if you connect two wires of load directly to the circuit otherwise don't. At my home I have only one wire per load coming to switch board and other wire is connected to common. I tried dozons of solution and tried altering the wires with different different combinations, nothing work. Finally I pulled one more wire from ceiling fan to switch board and then connected these two wires to this circuit to work circuit properly. Can you help me?

at you what frecquency in on main supply? 50Hz or 60Hz...in sketch must have freqStep=75; for 50Hz and freqStep=65; for 60Hzfor more details see https://arduinodiy.wordpress.com/2012/10/19/dimmer-arduino/

Hi, I want to dim the light using RF transmitter and receiver. For this I am using 433Mhz receiver and transmitter pair. What modifications are needed in the code to successfully dim the light using RF?

I am using 2 arduino boards, trying to send 1, 2, 3, 4 as message from the transmitter circuit. I am using 4 push buttons.

Made some modifications in the receiver code. It is receiving the codes as shown in the serial monitor but dimming is not happening. Please check if I've made the inputs properly.

Thanks.

I am using 2 arduino boards, trying to send 1, 2, 3, 4 as message from the transmitter circuit. I am using 4 push buttons. How do I change this part: void translateIR() // takes action based on IR code received

And I also want to dim the light to 8 steps. Here we have 16 steps. If I have to modify it to 8 levels (4 steps for increasing the brightness and 4 steps for decreasing), where the levels will stop by at 80%, 50% and 30% of the rated voltage (220V ac, 50Hz) what should be done?

Using the relay modules is not an option because I am concerned about the size of the circuit and cost effectiveness. I just want to know how to control Triac firing using RF. I have got a transmitter and receiver pair and want to incorporate it in the circuit posted by you. Your help will be really appreciated. Please give me some hint, how do I control the Triac firing resulting in Dimming Ac light using RF transmitter and receiver?
